If you're Chelsea Handler, you apparently get your dear friend, Reese Witherspoon, a nude selfie. That's exactly what the Chelsea Does star posted on Instagram -- posing completely naked except for a pair of black stockings -- to celebrate Witherspoon's 40th birthday on Tuesday.
"Happy Birthday @reesewitherspoon," Handler captioned the photo.

Handler, 41, is no stranger to showing some skin on social media. Just last week, she posted a shot of her derriere while filming her upcoming Netflix talk show, writing, "I did my first warrior dash today. This was pre-dash."
Meanwhile, Witherspoon threw a star-studded birthday party in Hollywood over the weekend, with guests including Jennifer Aniston, Kate Hudson, Nicole Kidman, Matthew McConaughey, and more -- plus, a surprise performance by Taylor Swift!
